These are photos of the filled in railroad trestles of the Rapallo and Lyman Viaducts, part of the New Haven, Middletown and Willimantic Railroad’s line from New Haven to Willimantic, forming part of a more or less direct route between Boston and New York. Here is some history of the two viaducts according to an informational sign along the trail:
The Rapallo Viaduct, located in East Hampton, was built in 1873 for two train tracks. It was a 1,380 ft long bridge located 60 feet above Flat Brook but due to the increasing weight of freight trains, the viaduct was filled in underneath the tracks in 1913.
The Lyman Viaduct, located in Colchester, was also built in 1873 as a 1,108 foot long bridge located 137 feet over Dickinson’s Creek. Due to the increasing weight of freight trains, the viaduct was filled in underneath the tracks in 1912-13.
